Explain how the exon/intron structure of genes contributes to the generation of new gene functions during evolution.
Temka [501]

Answer:

The exons may be defined as the coding region of the RNA that codes for the particular amino acid. The introns are the non coding region of RNA and must be removed in the final RNA product.

Exon shuffling result in the formation of new gene. The alteration of the exon and intron structure leads to the new gene function in evolution. The genes that are favored and conserved in the evolution perform new gene function. The genes that are selected against are deleted during the evolution.

Suggest appropriate sources of food to meet their requirements for a Newborn baby and child aged 6.
pashok25 [27]

Explanation:

Calcium . Helps build strong bones and teeth.

Fat. Creates energy, helps the brain develop, keeps skin and hair healthy, and protects against infections.

Folate. Helps cells divide.

Iron. Builds blood cells, and helps the brain develop. Breast-fed babies should receive iron supplements.

Protein and carbohydrates. They provide energy and fuel growth.

Zinc. Helps the cells grow and repair themselves

Your baby also needs vitamins such as:

Vitamin A. Keeps skin, hair, vision, and the immune system healthy.

Vitamin B1 (thiamine). Helps the body turn food into energy.

Vitamin B2 (riboflavin). Helps the body turn food into energy, and protects cells from damage.

Vitamin B3 (niacin). Helps the body turn food into energy and use fats and protein.

Vitamin B6. Keeps the brain and immune system healthy.

Vitamin B12. Keeps nerve and blood cells healthy, and makes DNA -- the genetic material in every cell.

Vitamin C. Protects against infections, builds bones and muscles, and helps wounds heal.

Vitamin D. Helps the body absorb calcium from food, and keeps bones and teeth healthy. Breast-fed babies may need a D supplement.

Vitamin E. Protects cells from damage, and strengthens the immune system.

What is the resistance of a 20-cm-long column of blood in this artery? assume that resistivity of blood is equal to 1.6 ωm.
Alinara [238K]
The way in which you need to solve this is by using the formula:
<span>R = ρL/A 
</span>That one is the formula that demonstrates <span>Resistance of a wire in Ω.
The formula can be explained like this: 
</span><span>ρ is resistivity of the material in Ω-m </span>
<span>L is length in meters </span>
<span>A is cross-sectional area in m² </span>
<span>A = πr², r is radius of wire in m 
As soon as you have your numbers, you can replace and proceed to get the asnwer</span>
